Azim Surani, a Kenyan‑British developmental biologist, is Director of Research at the Gurdon Institute and Marshall-Walton Professor Emeritus at Cambridge. He co-discovered genomic imprinting in mammals in 1984, revealing epigenetic and functional differences between parental genomes contrary to Mendelian genetics.
